How much is too much nitrate in the water? Young scientists discuss the question after they run their own nitrate tests. They also consider sources of nitrates and offer explanations for the levels.

Precipitation reactions are always interesting. How about one that forms a precipitate using a gas? Chemists of any age will enjoy this twist on a standard solubility lab. Partners observe the lack of interaction between sodium...

Two to four players receive seven cards each, with plants, animals, or nitrates depicted. They place what they have onto their own empty game board with the objective to complete a food chain. The game is a fun way to reinforce learning...

In groups, young environmentalists investigate water samples that are contaminated with different types of pollutants. Each group presents their findings to the class and fills out the "Types of Pollutants Chart." This lesson is meant...

What better way is there to introduce conservation of mass than a few simple experiments? Young chemists conduct two chemical reactions, take the masses of reactants and products, then compare their results to determine...

Mirror, mirror, on the wall ... who's the best chemistry teacher of them all? You'll get the vote for certain after your class completes the Silver Mirror experiment! Partnered pupils use Tollen's reagent and glucose to silverplate a...

If your class is learning about polyatomic ions and needs a fun way to study those chemicals, then a bingo game might be right up your alley. This bingo game is intended to boost memorization skills, specifically the names of tricky...

My room isn't messy — it's a scientific experiment in entropy! Scholars investigate entropy, enthalpy, and spontaneity through a guided procedure and set of questions. The lesson connects the Second Law of Thermodynamics, energy...

Antibacterial socks are a product of nanotechnology. An inquiry-based lesson plan asks collaborative groups to create their own antibacterial socks and then test them against other products on the market. The sock with the least...

Nanoparticles have toxic effects on plant and animal life—even though you can't see them. The second activity of a two-part series has young scientists conduct an experiment that exposes plant and animals to nanoparticle pollutants. They...

Student uses the Nitrate Ion-Selective Probe to measure the Nitrate ions concentration in water samples. In another method, student converts nitrate ions to nitrite and uses the Colorimeter to measure nitrite and calculate the nitrate...

In this limiting reagents problem, students are asked to determine the amount of silver nitrate dissolved in a solution by performing a reaction with solid NaCl. In this randomized activity, each student is given a different unknown...

A lab experiment, in a series of experiments, that investigates fisheries. In this lab, students test the effects of fertilizers and other pollutants on a model ecosystem. Students also examine 2 years of ocean color (chlorophyll...

Complete directions for a teacher demonstration in which the electrolysis of a solution of silver nitrate is viewed under a microscope. Helpful tips and a diagram of the apparatus and set-up is provided. Easily adaptable as a student lab...

This science fair project shows you what you need to make an endothermic reaction, the coldness of which is governed by the amount of ammonium nitrate used. The Science Buddies project ideas are set up consistently beginning with an...

Determine the concentration of silver ion in a Silver Nitrate solution using gravimetric analysis.
